Delivering Consistent Wireless Performance Across a Global Footprint

The constraint: 285-site scheduling logistics, varied physical environments, inconsistent wireless conditions, no uniform network baseline

Coordinating wireless surveys across 75 countries and 285 sites required extensive planning, scheduling, and logistics management. Each site presented different physical environments, wireless conditions, and network requirements, meaning no single survey approach or remediation template could be applied uniformly across the full footprint without first understanding what each location actually needed. Access, local site contacts, and equipment logistics all had to be coordinated across dramatically different time zones and operating conditions.

Without a consistent, repeatable methodology, the organization risked ending up with 285 disconnected site assessments rather than a coherent global picture of wireless performance — data that couldn’t be compared, prioritized, or acted on consistently. The scale also meant that any inefficiency in survey scheduling or reporting would compound quickly across such a large number of locations. The organization needed a delivery partner that could apply a consistent survey methodology, manage complex global logistics, and turn site-level findings into actionable, comparable recommendations across all 285 sites simultaneously rather than address them one at a time.

Our approach

A Data-Driven Wireless Assessment and Optimisation Model

As HCLTech’s specialist delivery partner, TECEZE implemented a structured wireless site survey programme combining advanced survey technology, expert consulting, and implementation support. Active and Predictive Wireless Surveys were conducted across the global site estate using Ekahau AI Pro and Sidekick, capturing detailed information about each site’s wireless environment rather than relying on generic assumptions about coverage. Survey findings were then analysed to identify wireless coverage, performance, and reliability considerations, with recommendations and remediation guidance tailored to individual site requirements instead of a one-size-fits-all fix. Where required, existing access points were repositioned, and new access points were installed to improve wireless coverage, reliability, and network performance at the sites that needed it most. A consistent survey methodology was applied across the entire 285-site footprint, giving TECEZE the ability to maintain delivery quality and SLA performance across diverse locations and operating environments rather than letting quality drift between regions.

From challenge to transformation, the solution included:

Comprehensive Wireless Surveys

Active and Predictive Wireless Surveys conducted across the global site estate using Ekahau AI Pro and Sidekick to capture detailed site-level wireless environment data.

Expert Consulting

Survey findings analysed to identify wireless coverage, performance, and reliability considerations, with recommendations tailored to individual site requirements.

Access-Point Optimisation

Existing access points repositioned where required, with new access points installed to improve wireless coverage, reliability, and network performance.

Standardised Global Execution

A consistent survey methodology applied across the 285-site footprint, maintaining delivery quality and SLA performance across diverse locations and operating environments.

Governance and Reporting Cadence

Operational transparency and stakeholder alignment are critical to program success. A layered governance model keeps program health and delivery quality visible:

Cadence Forum Focus
Weekly Survey Progress Review Sites completed, scheduling adherence, on-site logistics issues
Monthly Delivery & SLA Review SLA attainment, remediation status, access-point implementation progress
Quarterly Programme Governance Call Regional coverage trends, survey methodology refinements, HCLTech stakeholder alignment
As Needed Escalation Forum Site access issues, critical coverage gaps, remediation prioritisation

How Teceze Executes on This Engagement

HCLTech engaged TECEZE as its specialist subcontractor for the global wireless site survey programme. TECEZE was responsible for conducting Active and Predictive Wireless Surveys, providing expert consulting and recommendations, preparing Wireless Site Survey Reports, advising on remediation, and supporting access-point repositioning and new AP installation.

Looking ahead

Building a Stronger Foundation for Global Wireless Performance

The wireless survey programme provides a repeatable framework for ongoing network optimisation across the client’s global estate. The combination of structured site assessments, actionable recommendations, and implementation support enables future wireless improvements to be planned around measured network conditions rather than assumptions. With the survey methodology established across 285 sites and 75 countries, the client has a scalable foundation for maintaining wireless coverage, reliability, and performance as its network requirements evolve.
